Hinge

HINGE.

SPEIFICATION forming 'part of Letters Patent` N. 689,201, dated December 17, 1901.

4Application filed August 5, 1901. Serial No. '70,91 9. (No modell)v V'PATENT OFFICEJ To all whom it may concern:

Be it known that I, WLLIAM KOESTER, a citizen of the UnitedStates, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

My invention relates to that class of hinges in which the leaves are pivoted upon a removable bolt or pintle.

The object of my invention is to provide such a hinge with means whereby the movement of the hinge may be limited at will, so that the hinge may either be set so as not to open at all or may be set so as to open within a limited degree or may be set so that it can be only partially closed. This and such other objects as may hereinafter appear are attained by the devices illustrated in the accompanying drawings, in which- Figure lis an elevation of a' hinge fitted.

with the preferred form of my device. Fig. 2 is a plan view of the same looking from above. Fig. 3 shows the same hinge set in closed position. Fig. 4 is a plan view of the same, showing how the device may be set so as to lock the hinge in closed position. 5 isa diierent embodiment of my invention. Fig. 6 is a sectional view on the line 6 6 of Fig. 5 looking in the direction indicated by the arrows. Fig. 7 is a detail of the pintle and locking-disk, and Figs. 8 and 9 are details showing a modified form of the stop F.

Like letters `of reference indicate the same parts in the several figures of the drawings.

Referring by letter to the accompanying drawings, AA B are the leaves of a butt-hinge, which are pivotally mounted in the usual Vmanner upon a pintle C,Y which is provided at one end with a knob D.

E is a toothed disk provided with a number of teeth e of substantially uniform size, which are formed by notches e in the periphery of the disk.

F is a stopor tooth provided at one -point on the disk E and projecting beyond the teeth e. This disk is perforated at its center and mounted upon the pintle C.

The leaf A is cutaway adjacent to the disk E, so as to form a shoulder b, which in the opening and closing' of the hinge will clear v the teeth e, but will abut against the larger Y E is attached to the knob D on the upper end of the pintle C, sovthat by lifting the pintle C by the knob D the disk may be also lifted and rotated at will and returned to place, so that any desired notch e may engage the leaf B.

Ifthe disk E be set as shown in Fig. 2, the leaves may swing apart fromreach other within a quarter of a circle. If set as shown in Fig. 4, one leaf will be locked in the first notch e' adjacent to the stop F and the other leaf will be locked between the first leaf and the stop F, thereby securely preventing the leaves of the hinge from being opened at all.

Although in my preferred construction I attach the disk E to the pintle C, and preferably at the upper end thereof, the device will be entirely operative if the disk is only loosely mounted upon the pintle, and it is entirely practical to mount the disk upon the pintle at any pointin its length so long as the leaves of the hinge are suitably cut away to receive it. For instance, as shown in Figs. 5 and 6, the disk Cis mounted at a lower point upon the pintle, the leaves of the hinge being 'cut away to receive the disk, substantially as in the construction shown in Fig. 1. In order, however, to change the adjustment between the disk and the leaves of the hinge in the modified form of my invention, (shown in Fig. 5,) it is necessary tp withdraw the pintle from the hinge suiiiciently far to allow of disengagement between the leaves of the hinge and the disk E. The disk is then turned to any desired point and the parts are reassembled as before.

Instead of providing theY enlarged tooth or not constitute a departure from the spirit of my invention.

Having thus described my invention, what IOC) I claim, and desire to secure by Letters Patent, is=

1. The combination With a loose-pin hinge, of means mounted upon the hinge-pin for normally and positively engaging one leaf of the hinge,- and a stop upon said hinge engaging means interposed in the path of the other leaf of said hinge, substantially as described.

2. The combination with a hinge, of adjustable means mounted upon the hinge-pin for normally andpositively engaging one leaf of the hinge and also affording an adjustable stop for limiting the movement of the other leaf of said hinge, substantially as described.

3. The combination with a loose-pin hinge, of an adjustable toothed disk mounted upon the hinge-pin and normally in engagement with one leaf of the hinge, andy a stop upon said disk for limiting the movement of the other leaf of said hinge, substantially as described.

tle, of an adjustable notched disk, a leaf 30 mounted upon said pintle, and normally engaging a notch upon said disk, a second hingeleaf mounted upon said pintle and arranged v to rotate freely around the notched portions of said disk, and a stop upon said disk for limiting the movement of said second leaf, substantially as described.
